Grammatica Sed Populari Ex Usu Law and Legal Definition
Grammatica sed populari ex usu is a rule of interpretation which means ‘when there is no inference which leads to a different result, words are to be understood in their popular meaning.’ Generally, the terms of every written instrument are to be understood in their plain, ordinary, and popular sense, unless they have acquired a peculiar sense, distinct from the popular sense.
In Edgerly v. Barker, 66 N.H. 434, 450 (N.H. 1891), words are to be taken in their popular and ordinary meaning, unless some good reason be assigned to show that they should be understood in a different sense.
